Low performance

I am performing performance tests for my master's thesis and I am getting very low performance Symfony2 applications. This is a simple application, one query and some math.

Test results for the team:

ab -c10 -t60 http: //sf2.cities.localhost/app.php

Server Software:        Apache/2.2.20
Server Hostname:        sf2.cities.localhost
Server Port:            80

Total:        230 2642 2492.9   1778   17146

Before testing, I ran two commands:

php app / console --env = prod cache: clear php app / console --env = prod cache: warmup

The symfony validation page tells me that I just don't have the intl extension, so apc is probably fine.

My PHP version:

PHP 5.3.6-13ubuntu3.6 with Suhosin-Patch

Can someone give me advice on what else should I check in my env?
